摘 要:目的:建立高效液相色谱(HPLC)荧光法测定血浆中左氧氟沙星的浓度,研究盐酸左氧氟沙星片在健康人体中的生物等效性。方法采用随机交叉自身对照试验设计,24名健康男性受试者单次口服0.2 g盐酸左氧氟沙星片受试制剂或参比制剂,分别于不同时间点采集肘静脉血,采用HPLC荧光法测定血浆中左氧氟沙星的药物浓度。利用DAS 2.0软件计算药动学参数,评价两制剂的生物等效性。结果受试制剂与参比制剂的主要药动学参数 t1/2、tmax 、ρmax 、AUC0唱36和 AUC0唱inf分别为(6.71±0.95)h和(6.60±1.00)h;(0.85±0.30)h 和(0.79±0.28)h ;(2815.48±513.04)ng/ml和(3185.59±674.29) ng/ml;(17157.61±1949.07) ng · h/ml和(17425.06±2447.80) ng · h/ml;(18324.52±2019.41) ng · h/ml和(18540.41±2523.08) ng · h/ml。两制剂主要药动学参数统计学分析无显著性差异。受试制剂与参比制剂 AUC0-36、AUC0-inf和ρmax对数比值的90%置信区间分别为95.2%-102.5%、96.1%-102.2%和82.8%-94.9%。结论受试制剂与参比制剂具有生物等效性,为生物等效制剂。Objective To develop a HPLC-fluorescence method to determine levofloxacin concentration in plasma for studying bioequivalence of levofloxacin hydrochloride tablet in Chinese healthy volunteers .Methods A single-dose of 0 .2 g test or reference preparation was given to 24 healthy volunteers in a randomized crossover study .The concentrations of levofloxacin at different time points were determined by HPLC with fluorescence detection .The pharmacokinetic parameters were calculated using DAS 2 .0 software program .Results The main pharmacokinetic parameters of the test and reference preparation ,t 1/2 、tmax 、ρmax 、AUC0-36 and AUC0-inf ,were respectively (6 .71 ± 0 .95) h and (6 .60 ± 1 .00) h ,(0 .85 ± 0 .30) h and (0 .79 ± 0 .28) h , (2 815 .48 ± 513 .04 ) ng/ml and (3 185 .59 ± 674 .29 ) ng/ml ,(17 157 .61 ± 1 949 .07 ) ng · h/ml and (17 425 .06 ± 2 447 .80) ng · h/ml ,(18 324 .52 ± 2 019 .41) ng · h/ml and (18 540 .41 ± 2 523 .08) ng · h/ml .The statistical analysis showed that the main pharmacokinetic parameters between test and reference preparations were no significant differences .The 90% confidence interval of test and reference preparations AUC 0-36 、AUC0-inf and ρmax were 95 .2% -102 .5% 、96 .1% -102 .2%and 82 .8% -94.9% .Conclusion The test and reference preparations were bioequivalent .
